Alaska is divided into 30 boroughs and census areas, each serving as a regional division for local administration. Unlike most U.S. states, Alaska does not have counties. Instead, it uses a combination of organized boroughs (with local government) and unorganized boroughs (managed directly by the state).

There are 19 organised boroughs and 1 unorganised borough divided into 11 Census Areas.
